The listing title on Amazon, "Automaxx LED Display Power Inverter 650W 12V/230V Pure Sine Wave Manual Switch for DC/AC", is a little misleading as it doesn't actually have an LED display, but $10 for Pure Sine Wave inverter with 2 universal sockets is ridiculously cheap. My order arrived today, haven't had a chance to test it yet, but it looks like a solid build.
